Solution #00004188
Scope:
This solution applies to all Barracuda Web Filters, firmware 4.0 or higher
Answer:
The custom category will consider the domain name as listed when evaluating
policy. A subdomain will also be
considered as part of the parent domain name listing as long as the subdomain
is not explicitly included in a Barracuda Web Filter standard category. In such
cases where a subdomain should override its standard categorization the
subdomain should be listed explicitly in the custom category.
Example:
If domain.com is listed in a custom category, mail.domain.com will not be considered
part of the listing since it already belongs to the Web-based Email standard
category. However, xxx.domain.com will be considered part of the domain.com
listing in the custom category because is not already included in a standard
category.
